Abstract

In the dynamic oceanic ecosystem, several phenomena
and natural processes take place depending on the climatic
conditions. Of these, the physico-chemical and biologic a1
processes largely contribute to the organic productivity related to fisheries. It is well-known that environmental fluctuations will influence the fishery resources. The rhythmic processes taking place in nature will have its effects on living organisms. Deviation from the natural condition will reflect upon the fish productivity and its availability.
